* Other Suids: Pigs belong to the family Suidae. Other suids, like wild boars and warthogs, also squeal, although the specific sound might vary slightly.
* Young Animals: Many young mammals, like puppies, kittens, and even baby humans, make high-pitched squealing noises as a way of communicating with their mothers or signaling distress.
* Primates: Some primates, such as monkeys, can emit sounds that resemble squeals, especially when they are excited or agitated.
* Rodents: Guinea pigs and some other rodents can make squealing noises, particularly when they are startled or feeling threatened.
It's important to remember that these are just some examples, and the specific vocalization of an animal depends on its species, age, and individual personality.
While these animals may share a similar sound, it's still important to note the distinction between a pig's squeal and the sounds made by other animals. Pigs have a unique vocalization that is easily recognizable.
